Increasing unit range

I don't want an upgrade, I want an ability that increases the attack range of units (so I can put it on an item). I can not figure out a way to do this. I tried triggers, but it appears with triggers you can't change unit stats. Is this impossible without JASS or something?

it is impossible

You'll need multiple unit types.

You can't change the attack range of a unit with standard triggers.

or if possible that pipedream might be able to do an native for this in the native pack

only ways to change range of unit I know of is:

1) Long Rifles upgrade

2) use Orb to enable second long-range attack

3) I've heard WE Unlimited has set unit attack range trigger

I believe the ability you need is War Club.

I once helped with a map that used it for this purpose.

Yeah long rifles and improved bows, but, both are upgrades. I might go with the orb thing, only problem is that I plan on having more than one of these items with different increments.

How can I use war club to achieve it?

Also, this is not to allow melee to have ranged, but to have ranged have longer range. Once I have the ability I'm using triggers to do this. The item will have no effect on melee units.

About war club:

You need that the ability's owner has a second attack with a greater range, because this ability let you change temporaly from one attack type to another. So the "solution" would be giving to all the heroes in your map a second attack with an increased range.

Bleh, nevermind then. I guess I won't have this in my map.
